While feed tips constructed in accordance with the various embodiments of the present invention are illustrated in the environment of a continuous metal casting machine of the type employing spaced rolls such as disclosed in US. Pat. No. 2,790,216, issued on Apr; 30, 1957, to Joseph L. Hunter, it is to be expressly understood that the principles of the present invention may be embodied in feed tips for use with other types of casting machines employing spaced movable members between which the metalis cast.

The continuous casting apparatus disclosed in the Hunter patent is designed for continuous casting of strip material and includes a pair of cooled rolls rotating on parallel axes relatively positioned so that adjacent spaced surfaces of the rolls determine the thickness of the strp material cast. A feed tip located between and depending downwardly from the pair of rolls includes a discharge nozzle from which molten metal is discharged into the space between adjacent surfaces of the rolls, the length of the discharge nozzle determining the width of the strip cast. The discharge nozzle communicates with a cavity into which molten metal is introduced. In order to obtain an acceptable product for extended periods of production, it is necessary that the molten metal be continuously discharged from the nozzle uniformly throughout its length. Asimilar requirement is necessary in other types of continuous casting machines employing movable members between which the metal is cast, such as spaced moving belts, for example.

it is an object of the present invention to provide a feed tip for continuous metal casting machines of the type employing movable. members between which the metal is cast which insures continuous distribution of metal from the discharge nozzle uniformly throughout its length to obtain uniform solidification of the metal across the width of the opposed movingmembers such as rolls or plates, for example, within a wide range of casting temperatures to produce a consistently uniform product of high quality havinga more uniform grain structure, with the attendant advantages of reduced residence time, a casting rate commensurate with the cooling capacity of the castingmachine, faster start-up, simplified control, and longer life of the feed tip.

The foregoing objects of the present invention are achieved by the provision of baffles located in the cavity between the molten metal inletand the discharge nozzle in specific relation to each other, to the flow of molten metal into the cavity and to the contour of the walls of the cavity facingthe discharge nozzle, which co'act in controlling the direction of flow of molten metal through the cavity in sucha manneras to insure continuous distribution of molten metal to the nozzle uniformly throughout its length.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION With reference to FIGS. 1, 2 and 3 of the drawings, a feed tip 10 constructed in accordance with the one embodiment of the present invention is shown in combination with a continuous casting machine employing rolls l1 and 12 between which the strip 13 is cast and removed upwardly therefrom, as viewed in the drawing. The tip 10 includes an elongated, trough-like metallic structure made up of base plate 14, side plates 15 and 16 and end plates 17 and 18, which provides a housing for refractory material defining a cavity 19 for molten metal. The cavity 19 communicates with an elongated narrow nozzle 20 located between therolls l1 and 12. A conduit 21 feeds molten metal from a source, not shown, to a molten metal inlet 22 to the cavity 19; the molten metal inlet 22 being located adjacent a wall of the cavity 19 opposite the nozzle 20 substantially intermediate the length of the nozzle.

The refractory material forming the cavity 19, such as fibrous refractory material sold under the trade name MARINITE, may be made up of individual pieces including end sections 23 and 24 defining the ends of the nozzle 20, side sections 25 and 26 and triangular sections 27, 28, 29, and 30 having inclined surfaces 31, 32, 33, and 34, respectively. The inclined surfaces 31, 32, 33, and 34 together define the surface of the cavity 19 which faces the inlet opening 35 of the nozzle 20. The interior surfaces of the side sections 25 and 26 are inclined inwardly at 36 to merge with the inlet of the nozzle 20, the discharge opening 37 of the nozzle being located below the upper ends of the side sections 23 and 24, as viewed'in the drawing. The exterior surfaces 38'and 39 of the side sections 25 and 26 as well as the upper edges 40 and 41 .of the metal side portions 15 and 16 are shaped to have a radius of ourvature comparable to the radius of curvature of the rolls l1 and 12 to permit the tip to be closely positioned between the rolls. To simplify construction, the triangular section of refractory material 27 may be secured to an elongated, relatively thin block of refractory material 42 supported on an elongated metal plate 43 extending between the metal side walls 15 and 16 and secured thereto by any suitable means such as screws, not shown. The triangular section 30 may be supported in a similar manner by a metal plate 44 in an intervening refractory plate 45. Also, the triangular sections 28 and 29 may rest on a rectangular refractory block 46 supported by the base plate 14.

In accordance with the principles of the present invention, a plurality of baffles, which may comprise relatively thin strips of refractory material, are positioned in the cavity 19 in symmetrical relationship to the molten metal inlet 22 for cooperation with each other and with the inclined surfaces 31, 32, 33, and 34 to control the flow of molten metal from the molten metal inlet 22 to the nozzle 20. In the embodiment of FIGS. 1, 2 and 3, three pairs of baffles are provided, namely, baffles 50 and 51, baffles 52 and 53 and baffles 54 and 55. As shown in FIG. 3, the baffles extend transversely between the inside surfaces presented by the spaced walls 25 and 26. As shown by baffle 54, the baffles may have a length greater than the space between the spaced walls to be received by slots formed in the spaced walls 25 and 26.

The baffles are in specific relationship with each other and with the wall of the cavity 19 facing the nozzle 22 made up of the inclined surface portions 31, 32, 33, and 34. The inclined surface portions 32 and 33 extend from the molten metal inlet 22 longitudinally in opposite directions and diverge oppositely in a direction toward the nozzle 20 and terminate at transverse lines 56 and 57, respectively. The inclined surface portion 31 extends longitudinally from the line 56 in a direction away from the molten metal inlet 22 while diverging toward the nozzle 20 and terminating at transverse line 58 where the spaced walls 25 and 26 begin to converge in a direction toward the nozzle 20. The inclined surface portion 34 extends in the opposite direction from the line 57 while diverging in a direction toward the nozzle 20 and terminates at transverse line 59 where the inside surfaces of the spaced walls 25 and 26 begin to converge in a direction toward the nozzle 20. The angle of inclination of the inclined surface portions 32 and 33 is essentially equal as is the angle of inclination of the inclined surface portions 31 and 34; however, the inclined surface portions 31 and 34 are inclined at a smaller angle as compared to the inclined surface portions 32 and 33. The adjacent ends 62 and 63 of the pair of baffles 50 and 51, respectively, are spaced from each other to provide a slot 64 therebetween which extends transversely across the cavity 19 and which is located symmetrically with respect to the path of flow of molten metal from the inlet 22 in a perpendicular direction toward the nozzle 20. The adjacent ends 62 and 63 of the baffles 50 and 51 are oppositely inclined to accurately define the width of the slot 64. The baffle 50 extends from the molten metal inlet 22 along the length of the cavity 19 in a direction toward one end of the nozzle 20, the right-hand end as viewed in the drawing, in overlying relationship with a portion of the molten metal inlet 21 and a part of the inclined surface portion 32 and terminates at an end 65, essentially parallel to its end 62, in spaced relationship with the terminating edge 56 of the surface 32. In a similar manner, the baffle 51 extends from the molten metal inlet 22 in a direction toward the other end of the nozzle 20, the left-hand end as viewed in the drawing,

in overlying relationship with a part of the molten metal inlet and a part of the inclined surface portion 33 and terminates at a transverse edge 66 spaced from the terminating edge 57 of the inclined surface portion 32, the edge 66 being essentially parallel to the edge 63. The baffles 50 and 51 are oppositely inclined and extend from a region spaced inwardly of the liquid metal inlet 22 in a direction toward opposite ends of the nozzle 20.

Baffle 52 of the second pair of baffles 52 and 53, having terminating edges 67 and 68, is located between the baffle 50 and the right-hand end of the nozzle 20, as viewed in the drawing, in overlying relationship with the inclined surface portion 32 and the inclined surface portion 31. The baffle 52 is in spaced, essentially parallel relationship with the inclined surface portion 31. The edges 67 and 68 of the baffle 52 are inclined at angles essentially opposite to the inclination of the plane of the edge 62 of the baffle 50, and the edge 68 is spaced from the adjacent edge 65 of the baffle 50 by a longitudinal dimension substantially greater than the longitudinal dimension of the slot ,62. In a similar but opposite relationship, the baffle 53, having edges 69 and 70, overlies the adjacent parts of the inclined surface portions 33 and 34 in essentially spaced parallel relation with the inclined surface portion 34. The baffles 51 and 53 are longitudinally spaced by a dimension similar to the spacing between the edges 65 and 68 of baffles and 52 and the edges 69 and 70 lie in essentially parallel planes inclined at an angle opposite to the plane of the edge 63 of the baffle 51.

The baffle 54 of the third pair of baffles 54 and 55 overlies the space between the adjacent ends and 68 of the baffles 50 and 52, respectively, in essentially parallel relation to the baffle 52. The baffle 54 is spaced from the plane of the baffle 52 on the side of the latter baffle closer to the nozzle 20 by a distance essentially corresponding to the distance between the inclined surface portion 31 and the baffle 52. The terminating edges 70 and 71 of the baffle 54 lie in planes essentially parallel to the terminating edges 67 and 68 of the baffle 52. The baffle 55 is of similar configuration and is similarly located with respect to the baffles 51 and 53; the baffle 55 essentially overlies the space between the adjacent ends 66 and, 70 of the baffles 51 and 53, respectively, is essentially parallel to the baffle 53, is spaced from the plane of the baffle 53 on the side of the latter baffle closer to the nozzle 20 by a distance essentially the same as the spacing between the baffle 53 and the inclined surface portion 34, and its terminating edges 72 and 73 lie in planes essentially parallel to the terminating edges 68 and 69 of the baffle 53.

The baffles 50, 52 and 54, on the one hand, and baffles 51, 53 and 55, on the other hand, are symmetrically positioned with respect to a plane perpendicular to the nozzle 20 and passing through center of the path of flow of molten metal from the molten metal inlet 22 in a direction toward the nozzle. The pairs of baffles are similarly but oppositely inclined with respect to their disposition longitudinally of the cavity 19 and also with respect to the planes of their terminating ends. Baffles on opposite sides of the path of flow of molten metal from the molten metal inlet 22 lie in essentially parallel planes with the baffles 50 and 51 overlying the steeper inclined surface portions 32 and 33 being inclined at a slightly greater angle as compared to the other baffles.

With this construction, a portion of the molten metal entering the cavity 19 through the molten metal inlet 5 22 flows between the spaced walls 25 and 26 in a direction perpendicular to the nozzle through the slot 64, the quantity of metal flow through the slot being determined at least in part by thewidth of the slot. As the molten metal leaves the slot 64 and flows in a direction toward the nozzle, the flow diverges equally on both sides of a plane perpendicular to the nozzle and passing through the molten metal inlet 22 and comprises the molten metal fed to the center portion of the nozzle. The remaining molten metal entering the cavity 19 through the molten metal inlet 22 is essentially equally divided between flow into the space defined by the inclined surface 32 and the baffle 50, on the one hand, and flow in the space defined by the inclined surface portion 33 and the baffle 51, on the other hand. With respect to the molten metal flowing between the inclined surface portion 32 and the baffle 50, a portion of the metal flows into the space between the adjacent ends 65 and 68 of the baffles 50 and 52, respectively, in a direction generally toward the baffle 54, the inclination of the edge 65 of the baffle 50 and inclination of the edge 68 of the baffle 52 aiding in that result, while the remaining molten metal flows into the space between the baffle 52 and the inclined surface portion 31, the converging relationship between the surface 32 and the baffle 50 insuring the flow of molten metal adjacent the inclined surface portion 32 and into the space between the baffle 52 and the inclined surface portion 31 in a direction toward the right-hand end of the nozzle, as viewed in the drawing. With respect to the metal entering the space between the adjacent ends of the baffles 50 and 52, a part of the metal flows between the edge 65 of the baffle 50 and the edge 71 of the baffle 54, to supply molten metal to a portion of the nozzle 20, overlied by at least a portion of the baffle 54, to the right, as viewed in the drawing, of the central portion of the nozzle mentioned above, the inclination of the edge 71 of the baffle aiding in achieving the desired flow. The remaining molten metal flowing through the space between the baffles 50 and 52 is diverted by the baffle 54 for flow upwardly toward the nozzle 20 and in a direction toward the right-hand end of the nozzle including a component of flow generally parallel to the baffle 52, which influences the molten metal flowing from the space between the baffle 52 and the inclined surface portion 31 to insure the flow of molten metal along the surface 31 into the nozzle 20 at and adjacent to its right-hand end. The portion of the molten metal from the molten metal inlet 22 that flows into the space between the inclined surface portion 33 of the baffle 51 is divided and directed by the baffles 51, 53 and 55 in a similar manner. The flows of molten metal from around baffles, from between adjacent baffles and from between baffles and adjacent inclined surface portions, diverge as the flows progress in a direction toward the nozzle 20 to obtain uniform feeding of molten metal to the nozzle throughout its length while eliminating stagnant areas of molten metal in the cavity and with a relatively short and unifonn residence time, that is, the time between entry of molten metal at the molten metal inlet 22 and discharge of such metal from the nozzle.

DESCRIPTION OF FURTHER EMBODIMENTS OF THE INVENTION In the embodiment of the invention shown in FIGS. 4 and 5, the feed tip is supplied with molten metal through two conduits each feeding separate molten metal inlets and 101 located a quarter of the length of the nozzle from each end. Each molten metal inlet supplies molten metal for one-half the length of the nozzle 20. The surface of the cavity 19 which faces the nozzle 20 and is associated with each of the molten metal'inlets is constructed in a manner similar to FIG. 3 except in the present embodiment the surface extends throughout one-half the length of the nozzle. As shown, inclined surface portions 102 and 103 extends from the molten metal inlet 100 and oppositely diverge in a direction toward the nozzle 20, and merge with inclined surface portions 104 and 105, respectively, of less inclination, which extend in opposite directions. Similar inclined surface portions 106 and 107 extend from the molten metal inlet 101 and merge with similar inclined surface portions 108 and 109, respectively, of less inclination. The inclined surface portions 104 and 109 merge at the diverging surfaces of the cavity at opposite ends of the nozzle and the inclined surface portions and 108 merge at transverse line 110 located at the mid-point of the nozzle in spaced relation with the converging portion of the cavity. The inclined surfaces may be provided by triangular sections of refractory material supported by metal plates 111, 112 and 1 13 extending between the metal side walls of the housing in a manner similar to the construction shown in FIG. 2.

Two pairs of baffles are associated with each of the molten metal inlets 100 and 101. A first pair of baffles 114 and 115 are oppositely inclined in overlying relation with the inclined surfaces 102and 103, respectively, with their adjacent ends spaced from each other to provide a slot 116 located above the molten metal inlet 100. Baffles 117 and 118 of the second pair are spaced longitudinally of baffles 114 and 115, respectively, with the baffle 117 being in spaced parallel and overlying relation with the inclined surface portion 104 and with the baffle 118 being in spaced parallel and overlying relation with the inclined surface portion 105. Similar pairs of baffles 119-120 and 121-122 are associated with the molten metal inlet 101 and the inclined surface portions 106, 107, 108, and 109.

The pairs of baffles associated with the molten metal inlets 100 and 101 function in a manner similar to the pairs of baffles 50-51 and 52-53 of the embodiment of FIG. 2 and the edges of the baffles are similarly inclined. Thus, thepairs of baffles associated with each of the molten metal inlets cooperate with each other and their associated inclined surface portions to feed molten metal uniformly to one-half the length of the nozzle 20, the inclination of the inclined surface portions 105 and 108 to locate the transverse line 110 so as to insure unifonn distribution of molten metal in the central region of the nozzle. With this embodiment of the invention, it is possible to continuously obtain uniform distribution of metal to the nozzle throughout its entire length without utilizing a third pair of baffles as disclosed in FIG. 2 while obtaining reduced residence time and simplifying control of the casting operation.

In the embodiment of FIGS. 6 and 7, a single molten metal inlet conduit is provided at the mid-point of the nozzle 20, which feeds an internal manifold 131 extending in opposite directions to a pair of molten metal inlets 132 and 133 each located at a mid-point of onehalf the length of the cavity 19. The wall of the cavity 19 facing the nozzle is made up of a pair of oppositely inclined surface portions 134 and 135 associated with the molten metal inlet 132, and a pair of oppositely inclined surface portions 136 and 137 associated with the molten metal inlet 133. The inclined surface portions 134 and 136 terminate at opposite ends of the cavity 19 where the cavity begins to diverge in a direction toward the nozzle 20 and the inclined surface portions 135 and 137 merge at a transverse line 138 located at the midpoint of the cavity and spaced inwardly of the diverging portion 35 of the cavity in a direction away from the nozzle 20. The inclined surface portions 154, 155, 156, and 157 are defined by triangular blocks of refractory material which may be supported by metal plates 139, 140 and 141 in a manner similar to the structure of FIG. 3.

A pair of baffles 142 and 143 is associated with the molten metal inlet 132 and a similar pair of baffles 144 and 145 is associated with the molten metal inlet 133. The baffles 142 and 143 are oppositely inclined and overlie the inclined surface portions 134 and 135, respectively, and their adjacent ends are spaced from each other to provide a slot therebetween which is symmetrically positioned with respect to the flow of molten metal from the molten metal inlet 132 in a direction perpendicular to the nozzle 20. As shown more clearly in FIG. 7, the walls of the manifold 131 are shaped at 146 so that the molten metal flows from the molten metal inlet 132 in symmetrical relation with its physical shape. The pair of baffles 144-145 are similarly positioned with respect to the molten metal inlet 133 and the inclined surface portions 136 and 137. In order to control the flow of molten metal toward the central portion of the nozzle 20, baffles 147 and 148 are positioned in overlying relation with inclined surface portions 135 and 137, respectively. The baffles 147 and 148 are in spaced essentially parallel relation with respective inclined surface portions and are equally spaced on opposite sides of the transverse line 138.

In this embodiment of the invention, the relatively closer location of the molten metal inlets 132 and 133 to the nozzle 20 make it possible to continuously feed molten metal to the nozzle uniformly throughout its length with the use of a minimal number of molten metal flow control baffles.

FIGS. 8 and 9 of the drawings illustrate an embodiment of the invention in which a single conduit 160 supplies molten metal to an internal manifold 161 which conducts molten metal to a plurality of molten metal inlets 162, 163, 164, and 165 located at midpoints of quarter-length sections of the nozzle. The surface of the cavity 19 facing the nozzle 20 is made up of a plurality of pairs of oppositely inclined surface portions which diverge in a direction toward the nozzle 20 equal to the number of molten metal inlets with a pair of inclined surface portions being associated with each molten metal inlet. As shown, pairs of inclined surface portions 166-167, 168-169, 170-171, and 172-173 are respectively associated with the molten metal inlets 162, 163, 164, and 165. The inclined surface portions 166 and 173 merge with the end walls of the cavity 19 at opposite ends of the nozzle while adjacent inclined surface portions of adjacent pairs of inclined surface portions merge at transverse lines spaced from the nozzle. As shown, inclined surface portions 167-168, 169-170 and 171-172 merge at transverse lines 174, 175 and 176, respectively. The transverse lines 174, 175 and 176 lie in a common plane parallel to the nozzle and spaced from the converging portion 36 of the cavity in a direction toward the molten metal inlets. As in the previously described embodiments, the inclined surface portions may be provided by triangular blocks of refractory material supported by metal plates 177, 178, 179, 180, and 181.

A pair of longitudinally spaced, oppositely inclined baffles is associated with each of the molten metal inlets in symmetrical relation with the path of flow of molten metal from the inlets toward the nozzle. As shown, pairs of baffles 182-183, 184-185, 186-187, and 188-189 are similarly associated with molten metal inlets 162, 163, 164, and 165, respectively, and the re lationships will be understood by reference to the pairs of baffles 182-183. The adjacent ends of baffles 182-183 are spaced from each other to provide a slot therebetween disposed symmetrically with respect to the path of the flow of molten metal from the molten metal inlet 162 into the cavity 19 in a direction toward the nozzle 20. In this embodiment, the manifold 161 is not shaped so that the molten metal flows uniformly from center of each of the molten metal inlets and, in order to locate the slot between adjacent baffles in the path of flow of molten metal, the pairs of baffles are displaced from the geometric center of the molten metal inlets in the direction of metal flow in the manifold. The baffles 182-183 overlie a part of the molten metal inlet and a part of inclined surface portions 166 and 167, respectively, and are inclined in a manner similar to such inclined surface portions. In order to control the flow of molten metal to obtain uniform flow of molten metal to the nozzle 20, baffles 190, 191, 192, 193, 194, 195, 196, and 197 are associated with inclined surface portions 166, 167, 168, 169, 170, 171, 172, and 173, respectively. As shown, the baffles 190-197 overlie a medial part of respective inclined surface portions in spaced, essentially parallel relation therewith.

In each embodiment of the invention, there is associated with each liquid metal inlet a pair of inclined surface portions defining at least a part of the wall of the cavity facing the nozzle 20 and a pair of longitudinally spaced baffles to provide a slot therebetween symmetrically located with respect to the path of flow of molten metal from the molten metal inlet in a direction toward the nozzle with the baffles overlying a portion of the molten metal inlet and a part of one of the inclined surface portions. This arrangement selectively divides the molten metal entering the cavity from the molten metal inlet into a first portion passing through the slot and essentially equal second and third portions which flows between the baffles and their respective inclined surface portions to controllably direct the flow of molten metal in opposite directions toward the nozzle on both sides of the flow of molten metal through the slot. The provision of additional molten metal flow control baffles, determined by the number of molten metal inlets and the dimension between such molten metal inlets and the nozzle, provide for further control of the flow of molten metal in the cavity toward the nozzle to insure uniform distribution of molten metal throughout the length of the nozzle. All of the embodimodifications may be made in the embodiments shown when constructed with differently sized housings. For example, the internal manifolds shown in FIGS. 6 and 7 could be located exteriorly of the housing'so that each of the molten metal inlets could be similar to the arrangement shown in FIG. 3.
